book ideas, car security guide?

I've decided that I'm going to write a book or maybe two as an all-purpose reference for Car Security/Remote Starts/Convenience, and since this forum is full of people who care about the subject I think you guys and gals would be able to help me out with some ideas.

Right now I'm thinking 3 sections - one for customers (trying to learn a bit before going shopping), one for sales people (enough detail to help converse intelligently) and of course one for installers (I'd like this to be regarded as a good complement to MECP guides).  Levels of detail naturally increase with each section.

What would everyone like to see in such a book? There's not a stupid idea you can post here, honestly.  New installers especially I'd like to hear from since the technical section would be mainly towards you all.

Weird questions customers always have? Things that you think are lacking in product manuals? Vehicle/brand specific info? I'm planning on making at least part of this book(s) long enough to get really gory.

Thanks a bunch in advance as always.

Just stress that in most cases you get what you pay for.  If you purchase a $29 remote start unit and pay $29 to install it I can almost guarentee it will have shortcomings.

It would also be beneficial to explain to "customers" that every car is different, and as such, will require different parts.  It is a GREAT idea for the consumer to research THEIR vehicle so they know EXACTLY what parts are needed.  This will prevent shops from nickel and diming the customer who has no idea what all is needed to make things work correctly.

How will you be handling royalties?   :)

Royalties haha...that'd be a little presumptuous of me at this point.

I'm definitely going to stress install quality - and not buying "direct from Hong Kong distributors warehouses" on eBay.   

this is sure going to be a long task, but in the end it pays off to know you helped some individual.

I've thought of it...I don't know if you guys get ME mag at all, but they have a feature where they'll review a couple brand new vehicles...sometimes the DEI techs are supplying info for it, among others.

The thing there is that I'd like to get into more detail - for example, how much easier would it have made things if when the 2003 Saturn Ion or 2001 Chrysler minivans were introduced, someone in the industry wrote a thorough explanation of multiplexed ignition harnesses and how the automakers were starting to use them. Or of multiplexing in general, really.

Granted that those aren't exceptionally difficult vehicles to install on - but for those who were in the industry at the time it would be nice to have a detailed explanation to give to our customers, rather than 'the book says we need this extra part'.  And that's more info than I think could be put in a magazine article...however I could see publishing an annual update, or a detailed vehicle analysis for new models.

Immobilizers are another big thing for sure - how many customers and installers do you know who have no idea whatsoever about how they work, what cars have them, what the keys look like, and what it takes to bypass them?
